Ammo Momentum and Energy Chart - Ruger Forum
2008年4月3日 · Here's some popular handgun cartridge momentum ratings based on factory muzzle velocities. Semi-autos are rated in the most popular barrel length for the cartridge. Revolvers are rated in 4" barrel lengths except the 327 Fed is 3 1/16” and the 45 Colt is 7.5”.

2008年2月27日 · Energy is very important but it only tells half the story. If you want a real compairison between cartridges, momentum (measured in pounds feet per second or lb-f/s) is by far the better form of measurement. Here's a chart with some common cartridges and bullet weights. 45 ACP, 230 gr @ 850 fps = 27.9 lb-f/s 45 ACP, 200 gr @ 940 fps = 26.9 lb-f/s

Velocity vs Energy vs Momentum? - Ruger Forum
2018年5月2日 · It is simply bullet weight (in pounds) times velocity (in feet per second). The energy / momentum chart also has the formulas so you can compute your own loads. There's no such thing as a free lunch when it comes to the power of a cartridge. As velocity increases, momentum will increase. As bullet weight increases, momentum will increase.
Energy vs Momentum - Ruger Forum
2012年1月30日 · Momentum is only superior to exergy if you have a non expanding bullet and a relatively low velocity. Example 1500 fps 30 caliber fmj and 45 caliber fmj at that low a speed obviously the 45 caliber would be superior at over 2000 fps bullets can expand or yaw or tumble and that is greatly affected by velocity.Hence the excellent close up lethality of 5.56 mm non expanding that will tumble in ...
Odd Ammo Thoughts--Do We Tend To Overvalue Velocity?
2024年10月19日 · A much more authentic term is "momentum", derived from multiplying fps by bullet weight in pounds (7000 grains = 1 lb). As an example, the same 9mm cartridge noted above (115gr 9mm @ 1155 fps) has a momentum of: 115/7000 = .0164 times 1155 = about 19 lb-fs of momentum. 19 lb-fs is still overstated but is way more accurate than a whopping 341 ft ...

2016年5月30日 · There is a chart in the forum library that lists all the common handguns with factory load bullet weights and velocities. You will note in this chart .... a 357 Mag with a 125gr bullet falls about in the middle between minimum and maximum (25.9 lb-f/s) so it doesn't have to depend on high tech bullets to get the job done.

SP101 - 2 1/4 barrel - correct load - Ruger Forum
2008年11月10日 · Regular 357 Mag 158 gr loads rate just a tad better. No 38 Special loads come close to a momentum of 20 in a 2 1/4" barrel. There is an energy & momentum chart posted at the top of the Reloading Forum or you can compute momentum by multiplying velocity (in fps) by bullet weight (in grains) and divide the result by 7000.
380 in real life - Ruger Forum
2017年3月11日 · JohnR2, Your chart has absolutely no credibility .... the FBI chart does. The FBI certainly doesn't rate a 32 higher than any other handgun or a 357 Mag higher than a 44 Mag. I'm sorry but this chart totally defies common sense and science alike. In order of the above presentation with a few additions, here's what the FBI says: 25 ACP less than 10%
